The DPIO driver incorrectly assumes virtual addresses are always
64b long, which causes compiler errors when building for a 32b
platform.
Fix this by using explicit casts to uintptr_t where necessary.

Drop dependency on ARCH_LAYERSCAPE (which in turn depends on ARM64),
thus allowing this driver to compile on all architectures supported
by the fsl-mc bus driver.
This was compile tested on:
- powerpc (corenet_basic_defconfig, ppc64_defconfig)
- x86 (i386_defconfig, x86_64_defconfig, needs CONFIG_OF)
- arm64 (defconfig)

Seems you need to compile it on more things, based on the kbuild
warnings :(
Please fix up and resend.

I've added allmodconfig and the sparse endianness flag to my list of tests.
Will send a v2 early next week.
